  • Patent number: 4888363
    Abstract: An anhydrous cosmetic composition is provided comprising an emollient, a thickening agent, a solubilizer, and a working ingredient for enhancing the appearance of or otherwise imparting beneficial effects to the skin. The preferred working ingredient is Vitamin A, or a blend of Vitamin A and derivatives thereof. The composition is exceptionally pleasing and cosmetically appealing when topically applied to the skin's surface, is surprisingly percutaneously absorbent, and maintains the working ingredient stable for extended periods. As a result, lower concentration levels of working ingredients (Vitamin A) are utilized then would otherwise be necessary to achieve improved skin appearance effects, thus avoiding irritation sometimes associated with Vitamin A containing cosmetic preparations.
